The invention is a machine for printing, perforating and cutting a stripof paper as it is transferred from one roll to another.

The object of the invention is to provide a suitable device forconverting a roll of plain paper into small rolls of commode seatcovers.

Another object of the invention is to provide a machine embodying thecombination of printing, perforating, and partially c utting openings insheets of paper passing therethrough.

Another object of the invention is to provide a machine for printing andcutting a material that passes from one roll to another in which eachroll is provided with means for causing tension in the material.

A further object of the invention is to provide a tabulating device fora machine for converting rolls of paper into commode seat covers whichwill record the number of covers.

A still further object of the invention is to provide a backing for aperforating knife v which is the same shape as the knife so that it willperforate a thin crepe paper with a clean cut.

And a still further object of the invention is to provide a convertingmachine of the type described which is of a simple and economicalconstruction.

1With these ends in view the invention embodies a machine having a standfor holding a roll of paper at one end, means on the stand forfrictionally gripping the paper shaft, a frame to which the said standis attached, two sots of vertically positioned rolls on the said stand,one of the said sets of rolls having means for printing and perforatingpaper passing therethrough, the other set of rolls having suitable diesfor partially cutting openings in the paper, means for inking the saidprinting device, suitable feed rollers for the said paper, a

.shaft for a spool upon which the finished product is wound, means forcausing tension on the said spool, and suitable driving mechanism forthe various devices.

Other features and advantages of the invention will be seen from thefollowing description taken in connection with the drawings, whereinFigure l is a side elevation of the machine.

Figure 2 is a longitudinal section showing the rollers and drives.

Figure 3 is a plan view with parts omitted.

Figure 4 is a view showing a sheet of the printed and cut paper as it ispassing out of the die rollers.

Figure 5 is a view showing a portion of the perforating knife.

Figure 6' is a view showing a section of the die which forms a backingfor the perforating knife.

In the drawings the device is shown as it would be made wherein numeral1 indicates the main frame, numeral 2 the supply roll of paper, andnumeral 3 a tabulating device.

The frame 1 may be made as shown or of any suitable design and of anysuitable material. In the design shown it is made with the horizontalupper surface 4 to which the bearings of the main shaft are attached,which is supported on suitable legs 5 and 6.

The printing and perforating rolls which are indicated by the numerals 7and 8 are mounted in bearings 9 which are provided with uprights 1() inwhich the upper roll is mounted in blocks 11 so that its position may beadjusted in relation to the lower row. The other set of rollers whichform the dies are indicated by the numerals 12 and 13 and are mounted insimilar bearings which are indicated by the numerals 14 and providedwith uprights 15 in which the upper roller is adjustably mounted inblocks 16. It will be observed that type may be mounted in the roller 7as indicated by the numeral 17 which will engage a platen as indicatedby the numeral 18 in the roller 8 or so that it 90 will print upon thepaper which is indicated by the numeral 19 as the paper passes betweenthe type and platen. At the lower side of the roller 7 the type willengage ink rollers 2() and 21 which engage smaller rolls 95 22 and 23that engage a larger roller 24 which is inked by an ink roller 25 whichdips into an ink pan 26.

The die as shown in Figure 6 and indicated by the numeral 27 ispositioned in the side of the roller 7 as shown in Figure 2 so that theperfor-ating knife as indicated by the numeral 28 and positioned in theroller 8 will extend into it as both pass the center. As the paperpasses between the rollers the knife 28 will pass through the paper andmake a celan cut with the exception of the corners which as seen inFigure 6 and indicated by the numeral 29 are slightly rounded. lVith athin crepe paper of this nature it is absolutely necessary for the edgesof the knife to actually engage the backing or die in order to make aclean eut without tearin the paper.

The paper then passes from the rolls 7 and 8 to the rolls 12 and 13 inwhich the dies 30 and 31 are formed. The male member of the. die asindicated by the numeral and shown in Figure 4 is formed with a wideopening as indicated by the numeral 32 at one end and a very smallopening as indicated by the numeral 33 at the other end, and the sidesof the die are curved as shown to form cuts as shown by the lines 34 and35 on the piece of paper shown as comingA through the dies in Figure 4.The female member o-f the die as indicated by the numeral 31 is recessedin the roller 12 and the cutting edges are shaped exactly like the edgesof the member 30 so that a clean cut Will be made on the lines asindicated by the numerals 34 and 35A The devices will be printed on theflap formed between the lines on which the device is Cut as shown inFigure 4\ From the rollers 12 and 13 the paper will pass over a smallroller as indicated by the numeral 36 and from there to a spool 3.7 uponwhich the paper is wound and which is mounted onthe shaft 38.

The paper is supplied from a. large roll 2 which is mounted upon a shaft39 and snp-` ported in arms 40 which are pivotally attached to the legs6 and the frame 1 by pins 41 and the outer ends of which are supportedin adjustable stands 42 so that the outer ends may readily be raised orlowered as desired. The outer end of the. shaftl 39 is provided with awheel 43 and av band 44 may be placed around the wheel with one end.:it-- tached to a. member 45 by a. bolt 46 and the other adjnstablyattached to a projection 47 on the member 45 by a thumb screw 48 so thatthe pressure with which it grips the wheel 43 may readily be adjusted.It will also be observed that the member 45 is positionedl from the arm40 bya, thumb screw 49 and the end 50 of the member 45Iprojects intoa-slot 51 in the wheel 43 which is shown in dotted lines in Figure 3. sothat as the thumb screw 49 is screwed inward or out- Waxd it will movethe shaft 39. trairsvei-sallyv a. pair of rollers 51 and 52, passingover the roller 51, between the rollers and then under the roller 52 asshown in Figure 2. From the under side of the roller 52 the paper passesbetween the rollers 7 and 8 and then between the. rollers 12 and 13 andthen over the roller 36 to the spool 37. A pair of small rollers 53 and54 may be provided as shown in Figure 2 to feed the paper to the dieIrollers 12 and 13. These rollers are mounted in stands 55 ext-endingupward from the bearing 14.

The device may be operated by a belt 56 which may be driven from acounter shaft or motor or any other suitable means which will drive apulley 57 having a clutch 58 at one side which may be operated by a rod59 through a lever 6() or directly by the lever 60 so that it may beoperated from eitherside of the machine. The pulley 57 mounted upon ashaft 61 which extends through the frame and the opposite end of whichis provided with a hand wheel (32 by which the device may be started oroperated if desired. A small gear 63 is mounted on the shaft 61 and itwill be observed that this gear meshes with another gear 64 and the gear64 meshes with a gear G5 on the shaft of the roller 12. The gear 65 alsomeshes with a gear GG on the shaft of the roller 13 so that both rollerswill operate in unison and the gear 65 also meshes with a gear 67 on ashaft 68, the opposite side of which meshes with a gear 69 on the shaftof the roller 7 to operate the printing roller. The gear 69 meshes withanother gear 70 on the shaft of the roller 8 so that this roller willoperate in unison with the roller 7 and the gear 70 meshes with a gear71 on a shaft 72. The gear 7] also meshes with a gear 73 on a shaft 74which will operate the roller 52. The shaft 72 is also provided with asprocket 75 over which a chain 7G passes that operates a sprocket 7 7lon a shaft 78 of the ink roller 24. This chain passes over two idlersprockets 79 and 80. Another sprocket 81 is also mounted on the shaft 72which drives the sprocket 82 on a shaft 83 through a. chain 84 and itwill be observed in Figure 2 that the shaft 83 provided with a cam 84that engages a roller 85 on a lever 86 which is pivotally mounted on asupport 87 and the opposite end of which is attached to a latch 88having a prong 89 that will engage a ratchet 90 on the shaft of the inkroller 25 so. that as the shaft 83 ro"` ates it will operatethe latchthrough the lever 8G and rotate the roller 25 with an intermittentmovement. The lower end of the latch 88 is provided with a projection 91that is resiliently held by a. spring 92 which is attach edto a`projection at the lower end of the supporty 87. The spring will returnthe latch to the free position between each rotation of the cam.

The Shaft, tl is also provided with a pulincassa ley93 which will driveanother .pulley `94 on a shaftil through a belt .96 and the shaft 95 isprovided with a `freely mounted gear 95? which will mesh ywith a gear 98which .also meshes `with another gear 99 on the shait of the spool 37.The gear .97 iis resiliently held through the pulley .911 `by a spring100, the .tension of Which may Areadily be adzjusted lby a fhand wheel10i on .a screw 102 at the end .of the shaft 95. It will Vloe observedthat by turning the `hand Wheel the amount of friction against the gear97, may be readily adjusted so that the gear may be rotated to rotatethe `spool `with kconstant pressure on the paper. The shaft 38 is formedof two stub shaft-s extending into the ends of the spool With the end ofone which is indicated by the numeral 103 squared so that it Will causethe spool to rotate. Whereas at the opposite end the stub shaft is heldby a spring and the outer end is provided with a head 10aL so that Vitmay readily be Withdrawn to remove and replace .the spool.

The tabulating device which is indicated by the numeral 3 lis supportedon a bar 105V from the stand 15 .and provided with a rod 106 which iseccentrical-ly attached to `the end `of the yshaft of Vthe roller 13 as`shown Vat the point 1.07 so that as the shaft rotates each revolutionmay 'be recorded in the de vice.

It will be observed that the shaft 95 ex tends across the frame and theinner portion therein is threaded as shown at the point 108 and a splitnut 109 is mounted thereon in such .a manner that as the shaft ymakes apredetermined number of revolutions the nut 109 will engage a projection110 on the bar 59 and `move .the rod to such a position that the `clutchWill be free Vand the machine will stop.

It will be understood that changes may be made in the constructionWithout departing from `the spirit of the invention. `One of whichchanges may be in the design 0r Yarrangement of the frame as it isunderstood that any suitable fram-e may be used. Another may be .in theuse of other means for feeding the paper, another may be in the use ofother means for perforating and cutting the paper, another may be in theuse of other means for operating the spool upon which.

the finished prdouct is Wound, and still another may be in the use ofother means for automatically stopping the machine, It is alsounderstood that other minor changes may be made in the construction `andarrange* ment Without departing from the spirit of the invention.

The construction will be readily understood from the foregoingdescription. To use the device the machine may be arranged as shown andthe paper fed through it asfshown in Fig ure Y2. As the machine isstarted the die and printing and perforating rollers will be Yoperated:th-rough the gears vand the spool .upon which `the finished product iswound will also be operated by the holt 96 and through the intermediategears .as shown in Figures 1 and 3, :and it will be observed that .as`the Vspool 37 is operated, the gear 97 is frictionally held so that-the speed of 'the spool will be automatically regulated to provide aconstant tension on `"the :papers After .a pre-determined amount of `thefinished covers have been Wound upon `the spool the spool may bereino-ved `and `the roll of covers removed. It will therefore 'beobserved that ,this 4machine will readily convert a large roll of plainpaper into a plurality of smaller rolls `of commodeseat covers which areprinted, and have cuts forming flaps therein and are also perL foratedso that each cover may he torn off.
